The design and synthesis of pentafluorosulfanyl-containing heptad amino acid sequence was described. The three-dimensional conformation of the peptide was investigated by using CYANA (combined assignment and dynamics algorithm for NMR applications) and the integrated autoassignment. This study shows that the one of the diastereomers assumed a very tight coiled conformation in [D6]DMSO where both pentafluorosulfanyl
描述了含五氟硫烷基的七肽氨基酸序列的设计和合成。通过使用 CYANA(用于 NMR 应用的组合分配和动力学算法)和集成的自动分配来研究肽的三维构象。该研究表明,其中一个非对映异构体在 [D6]DMSO 中呈现出非常紧密的卷曲构象,其中两个五氟硫烷基均呈现向斜关系。受保护的七肽形成如此紧密的卷曲和五氟硫烷基团如此均匀排列的倾向暗示了五氟磺酰化氨基酸在促进构象控制中的效用。
